Aging processes leading to specific organ problems are not obvious in aging psittacines. In general, birds live long and age slowly despite their high metabolic rates and very high total lifetime energy expenditures. Most pathologic processes seen in older parrots are generally not specific for aging because they are seen in young birds as well. Pathologic processes that have a tendency to occur more in older psittacines are atherosclerosis and repeated injury processes, such as chronic pulmonary interstitial fibrosis, pneumoconiosis, liver fibrosis, and lens cataracts. Also, some neoplasms are more often seen at an older age.
导致特定器官问题的衰老过程在老龄鹦鹉中并不明显。一般来说，鸟类寿命长且衰老缓慢，尽管它们代谢率高且一生总能量消耗极大。在老年鹦鹉中看到的大多数病理过程通常并非衰老所特有，因为在幼鸟中也会出现。在老龄鹦鹉中更易发生的病理过程是动脉粥样硬化和反复损伤过程，如慢性肺间质纤维化、尘肺、肝纤维化和晶状体白内障。此外，一些肿瘤在老年时更常见。
